Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor unit is directly exposed to high surface temperatures to enable accurate measurement, then measurement precision is improved, but the reliability of the sensor deteriorates due to damage risk and reduced lifespan
Solution Approach 1:
The patent introduces a thermally conductive component as an intermediary between the high-temperature surface and the sensor unit. This mediator transfers heat from the surface to the sensor while maintaining the sensor at a safe operating temperature, enabling accurate measurement without direct exposure to damaging high temperatures.
2Adaptability or versatility
If wireless data transmission units and energy storage devices are integrated into the sensor unit for high-voltage systems, then adaptability is improved, but the reliability deteriorates due to reduced lifespan at high temperatures
Solution Approach 1:
The thermally conductive component serves as a thermal mediator that protects not only the temperature sensor but also the integrated wireless data transmission unit and energy storage device from high temperatures. This enables the electrical components to operate reliably while the sensor measures high surface temperatures.
Solution Approach 2:
The patent replaces wired data transmission with wireless data transmission to eliminate the need for physical connections in high-voltage environments. This substitution enables operation in electrically hazardous conditions while the thermal mediator protects the wireless components from thermal damage.
3Duration of action of stationary object
If the sensor unit is protected from high temperatures to maintain reliability, then the sensor lifespan is improved, but the measurement precision deteriorates due to temperature gradient
Solution Approach 1:
The thermally conductive component acts as a heat transfer mediator with optimized thermal properties. It conducts heat efficiently from the high-temperature surface to the sensor unit while maintaining a temperature gradient that protects the sensor, achieving both protection and accurate measurement through proper material selection and geometric design.
